I got my arduino like 6 months ago and it worked perfectly fine. I kinda learned how to use it but I decided to take a break for a while. Now when I try to use it, it doesn't want to work. I used it on a Windows XP when it worked and now I'm trying to use it on my laptop which is a Windows 7. It is a Duemilanove with an ATMega328. When I try to upload any code, it says,

Yes I have the right board selected, I only have COM3, my FTDI is current, I have looked at the troubleshooting, I tried running it in administrator, and it still won't cooperate with me. Any more ideas?
